Health-Related Quality of Life in Children with Vernal Keratoconjunctivitis in Malaysia

PURPOSE: There has been a lack of data on health-related quality of life (HRQoL) in children with vernal keratoconjunctivitis (VKC) from South East Asia. This study evaluated the levels (mean total score and subscales score) of HRQoL, comparing the VKC and normal children groups, and within the VKC severity groups.

METHODS: A cross-sectional study was conducted in two tertiary hospitals, specifically the pediatric ophthalmology services at Hospital Hospital Selayang and Universiti Sains Malaysia, spanning from 2019 to 2020. Participants aged 8 and 15 were categorized into two groups; those diagnosed with VKC and healthy children serving as the control group. Each participant completed the Quality of Life in Children with Vernal Keratoconjunctivitis (QUICK) questionnaire, consisting of 16 questions, divided into two subscales: 12 questions focusing on symptoms and four questions for daily activities.

RESULTS: A total of 240 children took part in the study, with 120 children diagnosed with VKC and another 120 in the control group. The mean age of participants with VKC was 11.21 (1.91) years, with a male predominance of 4:1 compared to females. Tearing (98.4%) and itchiness (98.3%) emerged as the most prevalent symptoms affecting HRQoL, while the most challenging activities were outdoor play (36.6%) and participation in recreational water activities (34.2%). The mean total score was significantly higher in the VKC group compared to the control group. Additionally, both the mean total score and all subscale scores were significantly higher in the severe type compared to the mild-moderate type.

CONCLUSIONS: VKC significantly reduce the HRQoL among Malaysian children, and the negative impact increases with the disease severity.
